As of October 3, 2016 Dropbox Basic (free) users can no longer use public links to render HTML content in a web browser. If you're a Basic user, and you created a website that directly displays HTML content from your Dropbox account, it will no longer render in the browser. The HTML content itself remains safe in Dropbox, and you can share it using any of our other sharing methods.

Effective September 1, 2017, Dropbox Plus and Business users can no longer render HTML content, and the Public folder and its sharing functionality have been disabled.

Accounts created after October 4, 2012

Dropbox accounts created after October 4, 2012 would not have had a Public folder. If you'd like to quickly share files you can use a shared link. Shared links work even if the person you're sharing with doesn't have a Dropbox account.
